Description

Technical Field

[0001] This application relates to the field of product testing, and in particular to a high-precision vibration measurement device for products. Background Technology

[0002] In the field of fan manufacturing, continuous technological advancements have led to ever-increasing demands for product quality. Fans, as common mechanical devices, are widely used in various scenarios, including industry, commerce, and daily life. Large HVLS (High Airflow, Low Speed) fans, for example, can be used for ventilation in large spaces such as aircraft hangars, and also for auxiliary cooling in data centers to reduce PUE (Power Usage Effectiveness). Their performance stability and reliability directly impact performance and user experience. Therefore, comprehensive and accurate performance testing of fan products is crucial to ensuring product quality. In particular, accurate acquisition of vibration data during fan operation is essential for evaluating structural stability, component reliability, and overall performance.

[0003] Currently, fan conduction vibration testing typically relies on manual loading and unloading of fans on the production line, followed by the use of tools to transfer the fans to the corresponding testing platform. This method is cumbersome and labor-intensive, as it depends heavily on manual operation. Furthermore, manual operation is prone to unpredictability and human error during testing. Moreover, the relatively slow speed of manual operation makes it difficult to meet the demands of large-scale production.

[0004] Current technologies that rely on manual testing of fan continuity and vibration have significant drawbacks. The low efficiency of manual operation leads to inefficient testing and prolongs the entire production process. Furthermore, high labor costs undoubtedly increase production expenses. In addition, the poor stability of the production process and the numerous uncertainties inherent in manual operation result in large errors in testing accuracy, making it difficult to guarantee the accuracy and reliability of test results and failing to meet the demands of rapid industrial automation. Summary of the Invention

[0005] To meet the need for convenient vibration testing of fan products in large fan production lines, realize automated product transfer and testing, and improve the stability and accuracy of testing, this application provides a high-precision vibration measurement device for products.

[0006] A high-precision vibration testing device for products includes a frame and a conveying mechanism, a transfer mechanism, a positioning and clamping mechanism, and a continuity testing mechanism disposed on the frame. The conveying mechanism includes a conveyor chain assembly, a carrier plate for placing products, and a limiting component. The conveyor chain assembly is disposed on the conveying path of the production line to convey the carrier plate containing products to a transfer station. The limiting component is used to limit the carrier plate at the transfer station. The transfer mechanism is used to clamp the products at the transfer station and transfer them to the testing station of the positioning and clamping mechanism. The positioning and clamping mechanism includes a positioning component and a clamping component. The positioning component is used to stably place the products, and the clamping component is used to press against the products. The continuity testing mechanism is used to electrically connect with the products to achieve conductivity and to detect and provide feedback on the vibration data of the products in the working state.

[0007] By adopting the above technical solution, the conveyor chain assembly of the conveying mechanism is set on the conveying path of the production line, flexibly utilizing the existing conveying capacity of the production line to automatically transport the material tray containing the product to the transfer station. Compared with manual loading, unloading, and product transfer, this greatly improves testing efficiency, reduces labor costs, and thus reduces production costs. The limiting assembly limits the material tray at the transfer station, ensuring the accuracy of the tray's position and providing a foundation for the subsequent transfer mechanism to accurately clamp the product. The transfer mechanism transfers the product from the transfer station to the testing station of the positioning and clamping mechanism, allowing the product to smoothly enter the testing process and automating product transfer. The positioning component of the positioning and clamping mechanism stably places the product, and the clamping component presses against the product, effectively fixing it and reducing product shaking during testing, thus improving testing stability and accuracy. The continuity testing mechanism is electrically connected to the product to achieve continuity, and detects and feeds back the vibration data of the product in the working state. It can accurately obtain the vibration data of the product during operation, which not only realizes the automation of product testing, but also improves the stability and accuracy of testing. It avoids the problems of long testing time, poor stability of production process, and large uncertainty in manual operation that lead to large test accuracy errors caused by the reliance on manual transfer and positioning of products in the existing technology.

[0008] Preferably, the conveyor chain assembly includes two sets of conveyor chains and a conveyor chain driver. The conveyor chain driver drives the conveyor chains to move. The conveying direction of the conveyor chains is consistent with the conveying direction of the production line. The conveying height of the conveyor chains is consistent with the conveying height of the production line. The material carrier plate is located between the two sets of conveyor chains, and its bottom is in contact with the top of the conveyor chains.

[0009] By adopting the above technical solution, since the conveyor chain drive drives the conveyor chain, and the conveying direction and height of the conveyor chain are consistent with the conveying direction and height of the production line, the carrier plate is located between the two sets of conveyor chains and its bottom contacts the top of the conveyor chain. This allows the carrier plate to move smoothly on the conveyor chain along with the conveying direction of the production line, thereby smoothly transporting the carrier plate containing the product to the transfer station, realizing continuous conveying of the product in the production line, and improving the conveying efficiency and stability of the product.

[0010] Preferably, the limiting component is disposed at the discharge end of the conveyor chain component. The limiting component includes a limiting block and a limiting cylinder. A limiting groove is provided on the edge of the material carrier plate. The limiting cylinder is fixedly disposed on the frame. The limiting cylinder drives the limiting block to extend into the limiting groove to achieve limiting.

[0011] By adopting the above technical solution, the limiting component is set at the discharge end of the conveyor chain assembly. When the carrier plate containing the product is conveyed to the transfer station by the conveyor chain assembly, the limiting cylinder fixed on the frame drives the limiting block to extend into the limiting groove due to the limiting groove on the edge of the carrier plate. This effectively limits the carrier plate at the transfer station, ensuring the positional accuracy and stability of the product during transfer. This facilitates the transfer mechanism to transfer the product to the testing station and prevents the carrier plate from shifting during the transfer operation. After the transfer mechanism removes the product from the transfer station, the limiting component releases the limiting on the carrier plate, without affecting the continued operation of the production line. After the product inspection is completed, the limiting component limits the carrier plate at the transfer station, ensuring that the carrier plate does not shift during the process of the transfer mechanism placing the qualified product on the carrier plate at the transfer station.

[0012] Preferably, the transfer mechanism includes a clamping member for opening and closing the product and a lateral movement drive member. The lateral movement drive member drives the clamping member clamping the product to move horizontally to the test station. The clamping member includes a clamping drive module and two sets of clamping plates. The clamping drive module drives the two clamping plates to move away from or closer to each other.

[0013] By adopting the above technical solution, the clamping drive module in the transfer mechanism can drive the two sets of clamping plates to move away from or closer to each other, thereby realizing the opening and closing clamping of the product. This flexible opening and closing method can adapt to products of different sizes and specifications, facilitating precise product gripping. Subsequently, the transverse drive component drives the clamping components holding the product to move horizontally to the testing station, realizing the rapid transfer of the product from the transfer station to the testing station. This avoids the tedious process of manual loading and unloading and transferring products, reducing the time and error of manual operation, thereby improving testing efficiency, reducing labor costs, and also avoiding testing accuracy errors caused by unstable manual operation, thus improving the accuracy and stability of the test.

[0014] Preferably, the inner side of the clamping plate is provided with an arc-shaped clamping groove.

[0015] By adopting the above technical solution, since the inner side of the clamping plate has an arc-shaped clamping groove, the arc-shaped structure is adapted to the shape of the product, which can increase the contact area between the clamping plate and the product, make the clamping force distribution more uniform, and thus clamp the product more stably, avoiding the product from shaking or falling during the transfer process, thereby improving the stability and safety of the product transfer process.

[0016] Preferably, the positioning and clamping mechanism includes a test platform and four positioning plates. The top of each positioning plate has a positioning groove, and the four positioning plates are evenly distributed around the test platform and surround the outer perimeter of the product.

[0017] By adopting the above technical solution, four positioning plates are evenly distributed around the test platform and surround the outer perimeter of the product. The top of the positioning plates is provided with positioning grooves. This layout allows the product to be surrounded by positioning plates from multiple directions. The positioning grooves can better match the corresponding parts of the product, thereby enabling more accurate positioning of the product, ensuring the positional stability of the product during the test, avoiding product displacement or shaking, and thus providing a more reliable basis for subsequent vibration testing and improving the accuracy of test results.

[0018] Preferably, the positioning and clamping mechanism further includes four clamping units, each corresponding to one of the positioning plates. Each clamping unit includes a clamping arm and a rotary cylinder, the rotary cylinder driving the clamping arm to rotate and press down to clamp the product to the testing station.

[0019] By adopting the above technical solution, the positioning and clamping mechanism is equipped with four clamping units that correspond one-to-one with the positioning plate. Each clamping unit includes a clamping arm and a rotary cylinder. Since the rotary cylinder can drive the clamping arm to rotate, when the product is in the testing station, the rotary cylinder's action causes the clamping arm to rotate to the appropriate position and press down, thereby stably pressing the product against the positioning plate of the testing station. This ensures that the product remains stable during the testing process, avoiding interference from product shaking that could affect the detection and feedback of product vibration data by the conductive testing mechanism, thus effectively improving the accuracy and reliability of product vibration testing.

[0020] Preferably, the positioning and clamping mechanism further includes a sensor, which is disposed on the test bench to sense the product at the test station.

[0021] By adopting the above technical solution, sensors are installed on the test bench, enabling them to detect the products at the test station. When a product is transferred to the test station, the sensors can promptly detect its presence, providing signal basis for subsequent continuity tests and other operations. This avoids unnecessary testing actions when no product is present, thereby improving the accuracy and efficiency of the test.

[0022] Preferably, the continuity testing mechanism includes a continuity probe and a probe driver, wherein the probe driver drives the continuity probe to press down to connect with the product interface of the testing station to achieve continuity.

[0023] By adopting the above technical solution, the probe driver can drive the conductive probe to press down. Since the direction of the conductive probe pressing down is towards the product interface of the test station, when it is pressed down to a certain extent, the conductive probe will connect with the product interface, thereby achieving conductivity and providing a basis for subsequent detection of vibration data of the product in working condition.

[0024] Preferably, the continuity testing mechanism further includes a triaxial vibration sensor and a sensing drive, wherein the sensing drive drives the triaxial vibration sensor to press down onto the product surface at the testing station to detect and provide feedback on the vibration data of the product in the working state.

[0025] By adopting the above technical solution, the sensing drive can drive the triaxial vibration sensor to press down onto the product surface at the test station. Since the product is in working condition, its vibration will be transmitted to the triaxial vibration sensor in contact with it. In this way, the triaxial vibration sensor can detect the vibration of the product in working condition and feed back the detected vibration data, thereby achieving accurate testing of the product's high-precision vibration.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The conveyor chain assembly of the conveying mechanism is driven by a conveyor chain drive component. The conveying direction of the conveyor chain is consistent with the conveying direction of the production line, and the conveying height is consistent with the conveying height of the production line. The carrier plate is located between two sets of conveyor chains and its bottom contacts the top of the conveyor chain. It can automatically convey the carrier plate containing the product to the transfer station. The limit cylinder of the limit component drives the limit block to extend into the limit groove on the edge of the carrier plate to limit the carrier plate. This avoids the tedious operation of manual loading and unloading and transferring of products, thereby improving testing efficiency, reducing labor input, and thus reducing labor costs and production costs. 2. The lateral movement drive of the transfer mechanism drives the clamping component controlled by the clamping drive module to clamp the product and move it to the test station. The positioning plate of the positioning clamping mechanism is evenly distributed around the outer circumference of the product on the test table. The rotary cylinder drives the clamping arm to rotate and press down to clamp the product to the test station. The whole process is automated, which reduces the interference of human factors and improves the stability of the production process. 3. The probe driver of the continuity test mechanism drives the continuity probe to press down to connect with the product interface at the test station to achieve continuity. The sensor driver drives the triaxial vibration sensor to press down to the product surface, which can detect and feedback the vibration data of the product under working conditions. It can accurately obtain the vibration amount of the product, improve the test accuracy, and ensure the accuracy and reliability of the test results. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application provides a high-precision vibration measurement device for a product, referring to... Figure 1 and Figure 2The system includes a frame 1 and, in sequence, a conveying mechanism 2, a transfer mechanism 3, a positioning and clamping mechanism 4, and a continuity testing mechanism 5, all arranged within the frame 1. The conveying mechanism 2 transports a carrier plate 22 containing product 6 to transfer station a. A limiting component 23 limits the carrier plate 22, ensuring it accurately stops at transfer station a, preparing it for subsequent transfer of product 6. The transfer mechanism 3 clamps and transfers product 6 from transfer station a to test station b of the positioning and clamping mechanism 4. The positioning and clamping mechanism 4 stably positions and holds product 6, ensuring its stability during testing and preventing vibration from affecting the test results. The continuity testing mechanism 5 is electrically connected to product 6 to achieve continuity and detect and provide feedback on product 6's vibration data, achieving automated high-precision vibration measurement of product 6. Each mechanism has a clear division of labor and works collaboratively, enabling automatic loading, unloading, and testing, reducing manual operation, and improving testing efficiency and accuracy. To more intuitively illustrate the internal structure, the outer frame of the frame 1 is not shown in the diagram; only the internal support structure of the frame 1 is retained.

[0031] Specifically, the conveying mechanism 2 in this embodiment includes a conveyor chain assembly 21, a carrier plate 22 for placing the product 6, and a limiting assembly 23. The conveyor chain assembly 21 includes two sets of conveyor chains and a conveyor chain drive. The conveyor chain drive is a motor, which drives the conveyor chains through gears. The conveying direction of the conveyor chain is consistent with the conveying direction of the production line, and the conveying height of the conveyor chain is consistent with the conveying height of the production line. This ensures that the carrier plate 22 transitions smoothly between the production line and the conveyor chain, avoiding jamming or tilting of the carrier plate 22 during the transfer process.

[0032] The carrier plate 22 is located between the two sets of conveyor chains to stably place the fan product 6, and the bottom of the carrier plate 22 contacts the top of the two sets of conveyor chains. When the conveyor chains rotate, they can drive the carrier plate 22 to move.

[0033] Reference Figure 1 and Figure 2The limiting component 23 is located at the discharge end of the conveyor chain assembly 21 in the conveying direction. The limiting component 23 includes a limiting block 231 and a limiting cylinder 232. A limiting groove 221 is provided on the edge of the material carrier plate 22. The limiting cylinder 232 is fixedly mounted on the frame 1. The limiting cylinder 232 drives the limiting block 231 to extend into the limiting groove 221 to achieve limiting. The limiting cylinder 232 can be a common single-acting cylinder or a double-acting cylinder, driving the limiting block 231 to move via air pressure. A single-acting cylinder has only one air inlet and relies on a spring for reset; a double-acting cylinder has two air inlets, enabling bidirectional movement. The shape of the limiting block 231 can be designed according to the shape of the limiting groove 221, and is usually a block structure. In other embodiments, the limiting component 23 can also be replaced by a structure such as an electromagnetic lock, using electromagnetic force to limit the material carrier plate 22. Electromagnetic locks have advantages such as fast response speed and convenient control, and are widely used in highly automated production lines.

[0034] Specifically, the transfer mechanism 3 in this embodiment includes a clamping member 31 for opening and closing the clamping of the product 6 and a transverse drive member 32. The transverse drive member 32 drives the clamping member 31, which clamps the product 6, to move horizontally to the test station b. The transverse drive member 32 is a linear motor, which has the characteristics of high speed and high precision, and is suitable for occasions with high requirements for transfer speed and precision. The clamping member 31 includes a clamping drive module 311 and two sets of clamping plates 312. The clamping drive module 311 can be a transmission mechanism driven by a cylinder or a motor, driving the two clamping plates 312 to move away from or closer to each other. The cylinder drive has a simple structure and fast action; the motor drive can achieve more precise control. The inner side of the clamping plate 312 is provided with an arc-shaped clamping groove 3121, which can better fit the shape of the product 6 and improve the stability of clamping. For example, for a round fan product 6, the arc-shaped clamping groove 3121 can better wrap the product 6 and prevent the product 6 from falling off during the transfer process.

[0035] Reference Figure 1 and Figure 3 Specifically, the positioning and clamping mechanism 4 in this embodiment includes a test platform 41, four positioning plates 42, four clamping units 43, and a positioning sensor 44. The top of each positioning plate 42 has a positioning groove 421. The four positioning plates 42 are evenly distributed around the circumference of the test platform 41 and surround the outer periphery of the product 6. The positioning plates 42 are made of metal, which has high strength and stability, ensuring accurate positioning. The shape of the positioning groove 421 is designed according to the positioning requirements of the product 6, typically being a groove matching the shape of the product 6. The arrangement of the positioning plates 42 allows the product 6 to be accurately placed on the test station b.

[0036] Reference Figure 3 and Figure 4The clamping unit 43 is configured in a one-to-one correspondence with the positioning plate 42. The clamping unit 43 includes a clamping arm 431 and a rotary cylinder 432. The rotary cylinder 432 drives the clamping arm 431 to rotate and press down on the product 6 to the testing station b. The rotary cylinder 432 is pneumatically driven, causing the clamping arm 431 to rotate around its axis, thus pressing down on the product 6. This rotary pressing method provides significant pressure, ensuring the product 6 is stably fixed on the testing station b. A positioning sensor 44 is installed on the testing table 41 to sense the product 6 at the testing station b. The positioning sensor 44 can be a photoelectric sensor or an infrared sensor. When the product 6 arrives at the testing station b, the sensor can detect it promptly and send a signal so that the control system can perform subsequent operations. A displacement sensor 45 is also provided at one end of the test station 41 near the conveyor chain. The displacement sensor 45 is located between the transfer station a and the test station b. It is used to sense whether the product 6 is transferred from the transfer station a to the test station b or from the test station b to the transfer station a. The limit cylinder 232 drives the limit block 231 to extend into or out of the limit groove 221 based on the information detected and fed back by the displacement sensor 45.

[0037] Reference Figure 4 and Figure 5 Specifically, the continuity testing mechanism 5 in this embodiment includes a continuity probe 51, a probe driver 52, a triaxial vibration sensor 53, and a sensing driver 54. The probe driver 52 drives the continuity probe 51 to press down and connect with the product 6 interface at the testing station b to achieve continuity. The probe driver 52 can be a cylinder or an electric push rod, which drives the continuity probe 51 to move up and down. Cylinder drive has the characteristics of high speed and high force; electric push rod can achieve more precise position control.

[0038] Reference Figure 4 and Figure 5 The sensor drive 54 drives the triaxial vibration sensor 53 to press down onto the surface of the product 6 at the test station b to detect and provide feedback on the vibration data of the product 6 under working conditions. The sensor drive 54 can also be a cylinder or an electric push rod, etc. The triaxial vibration sensor 53 is an existing sensor that can simultaneously detect the vibration of the product 6 in three directions, providing more comprehensive vibration data.

[0039] The implementation principle of this embodiment is as follows: The high-precision vibration testing equipment for product 6 achieves an automated process from conveying to testing through the coordinated work of various mechanisms. Conveying mechanism 2 conveys product 6 to transfer station a, limiting component 23 ensures the accurate position of the carrier plate 22, transfer mechanism 3 transfers product 6 to testing station b, positioning and clamping mechanism 4 stabilizes and clamps product 6, and conduction testing mechanism 5 performs continuity testing and vibration data detection. Compared with existing technologies, this reduces manual operation, improves testing efficiency and accuracy, lowers production costs, and enhances the stability of the production process, better adapting to the development needs of industrial automation.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
